AUTOMOBILE HEADLIGHT,

Application filed November 5, 1924,.Se'ria1 no. 747,942. Renew ed'Nove mber 5, 1927.

My invention relates'to new and useful improvements in vehicle headlights, and has for its object to provide'a headlight which will "so confine and direct the rays'of' light emanating from the lamp and reflector, that while said rays will serve to clearly illuminate the entire road, on both sides, and for a long distance ahead, yet to retain such control'oversaid rays that they will create no glare, which will reach theeyes of an approaching motoristor pedestrian, Whether in front, or onthe' side.

Her'etofore the lamps as well as the specially constructed lenses, designed to overcome this blinding effect of the strong rays, have in diminishing the glare, also cut down the amount of light projected by the lamp and none have succeeded in satisfactorily eliminating the dazzling glare, from the bulb or the reflector. or from both.

To accomplish this end, I have constructed a headlight which serves to effectually con-,

ceal the sources of the light,'and at the same time to so direct the rays, that the entire road surface will be atall times satisfactorily .illuminated, without the blinding glare which renders the motor headlights now in gen eral use, both disagreeable and at times dangerous.

With the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel features herein set forth, illustrated in the accompanying. drawings and more particularly pointed outin the appended claims.

Referring to the drawings, in which'numerals of like character designate similar parts through'the several views; 7

Fig. 1 is a sectional view of the headlight.

Fig. 2 is a view looking down upon the light, showing the translucent deflecting por-- tion of the top, and. the horizontal'p'artition and inclined plate in dotted lines, and

Fig. 3 is a front view of the light.

In the drawings, 1 designates a lamp comprising an ordinary reflector 2 and bulb 3, the edges 4 of said lamp extending longitudinally for a slight distance and being adapted to fit firmly into the elongated hood 5 which at the rear end is cylindrical and at the other end substantially U-shape as shown at 6, Fig. 3. This hood 5'is composed of metal with an inner surface of a nonreflecting character, having inserted inv the employed for this purpose.

dust or rain, it may bedesirable to provide a lens or trans-- portion of the top at the end 6, a window 7' of translucent material, preferably glass, of any desired color or sha'de,frosted or similarly treated to render it non-reflecting and non-transparent forthe purposes to be hereinafter described. This translucent window 7 is setjat an angle tothe rays of light, and downwardly toward the frontand forming the upper part of the mouth 8 of the hood 5, as'shown in Fig.1. 1

'In this hood 5 at approximately'its longitudinal center, I provide a partition 9,preferably of thin metal, non-reflecting on top and reflecting on its lower surface, which is set longitudinally to the rays of light, and

parallel with the bottom of said hood, run-v ning substantially the entire length of the hood. Below this partition 9, I provide a second partition or plate 11, downwardly inclined toward the end 6 of the hood. 5. Said plate may be composed of thin metal,

but is preferably made of some translucent material similar to they window 7. In this particular embodiment of my invention, I have shown lugs 10, on the'inner surface of the hood '5, for securing the partitions in place, but any suitable means may be In order to exclude any lucent cover 12, for the mouth 8 of the hood. 1 The assembled headlights aresecured to the forward end of av vehicle by any desired means, with the reflector-end slightly higher than the mouth end, thus causing the deflected translucent top 7 the horizontal partition 9 and the inclined plate 11 to'effectually conceal the sources of light, namely the bulb and reflector from .the line of vision X, and avoid all glare. The translucent portion 7 of the top of the hood and the, platell, will allow a certain amount of softened light rays to pass through and project from the upper and lower portions of the hood 5 as indicated by the dotted lines in Fig. 1. These latter rays will reach the eyes of an approaching driver, but are not translucent top 7, the horizontal partition 9 and the inclined plate 11, as shown by the line X in Fig. 1, while the softened rays will produce a glow which is beneficial to both drivers.

From the foregoing, it is believed that my invention may be clearly understood without further description, it being borne in mind that, numerous changes may he made in the details of construction Without departing from the spirit of the invention as cisclosed in the appended claims. For instance, I may'construct my lamp so that the entire; top of the hoodwill he translucent,

1 or afthird plate or partition may introduced. within the, hood. 7

Itis, also obvious that the lamp 'body and hoodv maybe integral, although the construction hereinahove described preferred, in

order that the bulb and reflector may he removed for adjustments, or used for a troubil ig t, in cas f ne i What, I claim and desire to secure by Lete s te t: is

' 1. A: vehicle headlight comprising a lamp,
